Application Electrical panels, test equipment, power supplies, trainers, laboratory equipment
ELCOM specifically lists the BTI-30 as 250 V / 30 A, with 5 mΩ maximum initial contact resistance, 1000 MΩ minimum insulation resistance and 2 kVAC one-minute dielectric test.
Dimensions
The manufacturer's BTI-series drawing gives the BTI-30 mounting geometry as:
Maximum body diameter: approximately 35 mm
Minimum body diameter: approximately 26.5 mm
Panel cutout: approximately 19.2 mm
Panel thickness: 2.5 mm maximum
Thread: No. 1 BA
Entry: approximately 4.0 × 20.0 mm deep
Overall drawing dimensions: include approximately 28.5 mm body/depth dimension depending on the reference point.
Important: For catalogue/website use, I recommend listing the dimensions directly from the manufacturer's drawing rather than estimating the overall assembled length from the photograph.
Ordering / Colour Codes
For the standard BTI-30 series:
Code Colour / Version
BTI-30-03 Black, Non-RoHS
BTI-30-04 Red, Non-RoHS
BTI-30-05 Blue, Non-RoHS
BTI-30-06 Yellow, Non-RoHS
BTI-30-07 Green, Non-RoHS
BTI-30-V2 RoHS version
The manufacturer's datasheet also identifies BTI-30-A and related variants with different terminal-plating configurations.
Key Features
Heavy-duty 30A binding post
250V AC electrical rating
Front-panel mounting
Screw-type terminal construction
Suitable for 4 mm banana plug/test leads
Brass/copper-alloy current-carrying parts
Nickel-plated terminal construction
Nylon/ABS insulating body
Available in multiple colours for polarity identification
Compact panel-mounted design
Suitable for electrical test and measurement applications
A third-party listing also identifies the BTI-30 as a 4 mm plug-size binding post, consistent with its common use as a banana/test terminal.
Typical Applications
Laboratory power supplies
Electrical trainer panels
Test & measurement equipment
DC/AC power supply terminals
Electrical testing points
Industrial control panels
Battery/test equipment
Solar training and electrical demonstration equipment
Audio/electrical equipment
High-current test connections
For example, Maharashtra's government electrical-training specification lists BTI-30, 30A red and black terminals as high-voltage test points for electrical trainers.
